Picked up a pair of 59 AB's,both have water damage..this is the worst,yarded the head on the other side at it was nowhere near as bad,the one piston i could read has STD stamped in it,the bore does have a slight ridge.the second one isn't as bad either and shows a piston .020 over..neither decks look cut,and valve protrusion where I can tell doesn't look too bad.
the way I see it I can go as far as .100 over to clean up the bores,deck the block,cut or fit some new seats but Im new at saving something like this..what do you think?
